I had a real hard day with mine yesterday.
It was the third time I used it, single lube groove 45 acp with 50/50 lube, air cylinder, and heater. Kept getting spots on the nose. So I started making adjustments, one at a time, till I was ready to throw it in the garbage can. Lube would still push out the holes in the die with the handle in the raised position after sizing a boolit. I found this out by pushing the sized boolit through the die with a wood dowel just enough to push the boolit free of the die but not to stroke the lube pump. After the boolit passed the holes, lube would creep out. The next boolit run through, would then pick this up on the nose. I eventually got the temp and the air pressure settings low enough to stop this. I found there is a fine line between having these right. Temp needs to be just high enough to soften but not melt the lube, and air pressure was working well at a little less than 20 psi.
I could turn the air pressure up a little and make the lube seep past the holes in the die. With the temp too high, I got an even bigger mess.
I am going to try a harder lube as soon as it arrives, so I will have to go through this again, but might not take as long this time.
I have a electrical background and see a huge benefit in adding a better temp control on the base heater. Then you could set the temp to a repeatable setting each time and record this temp for each lube. Maybe a little anal and pricey, but would save time and maybe help others. What do you all think?
